IMPROVEMENT iN NiIDDLINGS-PURIFIERS.

Specification forming part of Letters Patent No. 157,169, dated November24, 137/1; application tiled J une 3,

To all whom -it may concern Be it known that I, ABRAHAM FULTON, ofOlney, in the county of Richland and in the State of Illinois, haveinvented certain new and useful Improvements in Middlings-Purier 5 anddo hereby declare that the following is a full, clear, and exactdescription thereot', reference being had to the accompanying drawingsand to the letters of reference marked thereon, making a part of thisspecitication.

The nature of my invention consists in the construction and arrangementof a middlingsforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to dering to theannexed drawings, in which- Figure 1 is a perspective view of mymiddlings-purier, and Fig. 2 is a transverse vertical section of thesame. l

A represents a box of any 'suitable dimensions, containing` the reel.This reel is composed of a central shaft, B, provided with radial arms OO, which support the ribs D D. E represents the bolting-cloth, which isfastened to and runs from the inside of one rib to the outside of thenext rib, causing the middlings to slide over the rib, instead of beingcar1ied up and dashed about as in ordinary bolting-reels. 'Io that sideof the reel which is moving upward is applied a brush, d, extending theentire length ot' the reel and attached to arms Gr G, which are hingedor otherwise flexibly connected to the box, so as reel, and keep thecloth clean. On one side ot' the reel, in suitable bearings, are placedthe journals of a bar or shaft, H, from which arms I I extend over thetop of the reel. o ne end of the shaft H is an arm, J, which projectsover a rim, K, attached to the head of the reel, said rim being providedwith projecting 'teeth b b, corresponding in number and location withthe number of the sides and ribs of the reel. As the reel revolves, theknocker, thus construct-ed, is raised by every tooth b acting insuccession upon the arm J, andas the teeth pass from under said arm theknocker falls down and strikes each rib as it passes over the center atthe top, thereby loosening all particles that may adhere to the cloth.

For a thirty-inch reel the speed should not be over twelve revolutionsper minute 5 and for reels of different sizes it should beproportionately greater or less, as the case may be.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In combination with the toothed rim K upon the reel, the rock-shaftH, provided with knockers II, and the operating-bar J, all constructedsubstantially as and for the purposes set forth.

2. rlhe combination, with the reel B O D E, of toothed rim K, rock-shaftH, with knockers I I and bar J, and the gravitating brush Gr el, allsubstantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 30th day of April, 1874.
